Negative emotions can influence food intake. Leptin (an anorectic hormone) levels may change in response to psychological stressors. This study aimed to explore the relationship between leptin and food intake triggered by negative emotions in overweight women. Two groupswere studied: normal weight women (n = 21) and overweight women (n = 23). Both groups were exposed to videos to stimulate negative and neutral emotions followed by application ofthe Subjetive Analog Scale. Plasma leptin levels were evaluated before and after exposure to the videos. Subsequently, a brunch containing sweet and salty foods was offered to simulatea high food availability environment. Results show that when exposed to negative emotions there was an increase in food intake (normal weight: p=.010 / overweight: p=.005). There was no change in plasma leptin levels in normal weightand overweight women. Negative emotions promotedan increase in energy intake in both groups. The results reinforce the integration of biopsychosocial aspects involving emotions and food intake.
负面情绪会影响食物摄入。瘦素（一种食欲抑制剂激素）水平可能会因心理应激源而发生变化。本研究旨在探讨超重女性的负面情绪引发的瘦素与食物摄入之间的关系。研究了两组人群：正常体重女性（n=21）和超重女性（n=23）。两组人群都观看了视频以刺激负面和中性情绪，然后应用主观类比量表。在观看视频前后评估了血浆瘦素水平。随后，提供了一顿包含甜食和咸食的早午餐，以模拟高食物供应环境。结果表明，当暴露于负面情绪时，食物摄入量会增加（正常体重：p=.010/超重：p=.005）。正常体重和超重女性的血浆瘦素水平没有变化。负面情绪会促使两组人群的能量摄入增加。这些结果强调了涉及情绪和食物摄入的生物心理社会因素的综合作用。
